I have to do a 20 min seminar in my grade 11 bio class thats worth 20% of my final grade. We can write it on any biology topic so i want to pick something interesting.
Anything off the top of your heads?

I have to do a 20 min seminar in my grade 11 bio class thats worth 20% of my final grade. We can write it on any biology topic so i want to pick something interesting.
Anything off the top of your heads?
do some type of cancer. SOOOO much info out there since it is a very aggresively studied disease..i did a 30 page independent project on brain cancer and used 10 articles from doctor / medical magazines and journals to cite from. easiest 20+ paper i ever did..but yeah, cancer - pick a type.
GL bro.
All good idea's, thanks people.
Id like to stay away from cancer and topics like that though. I want to pick something that i can actually enjoy researching, some cool concepts and stuff.
i mean sex is like biology... sooo you could research the shit out of boning and present it to your class... chicks will totally dig it hahahah
seriously though
Lol i know your serious.
I could do it like on erections (no homo) and make it really akward for everyone in the class.
AIDS, 10th grade I did a 5000 word essay on it. It was pretty easy and interesting.
Or gene mutation is pretty interesting.
A few good ones in here, any more?
Im pretty interested in things that would have to do with enhancing animals or humans (ive read, although i forget where, that in some countries they are testing how to rpoduce better soldiers)
Bascially anything pretty cool, i was also thinking of possibly doing a project on autistic savants.
haha yes i ment something more along the lines of the second thing you mentioned. I dont mean some robo-cop type soldiers. Im not that gulible.
Then again its not that hard to believe that they are working on things such as that, i mean do you realize as the public how easy it would be for a government to hide projects liek that from us, i mean its obvious they do. They could know about the world ending tomorrow and just not tell us. As the general public we are pretty much left in the dark.
lol but whatever, were not talking conspiracys here.
Stolen from my sister..
Monkeypox Virus
Report by: Kamber Biss
Abstract
I wanted to write a research paper of a rare virus that isn’t well known by most people in the United States due to its low infectious rate in the U.S. I did some research on the internet on rare viruses, and came across Monkeypox virus. It interested me because it was originally found in monkeys in 1958, and was thought to only be found in monkeys until the virus was found in an African squirrel, which is now believed to be the monkeypox virus’s natural host. The monkeypox virus has very similar symptoms of smallpox, but usually less severe. Monkeypox has most reported cases in western and central Africa near the tropical rain forest. Most cases were reported in Zaire.
Monkeypox Virus
A virus is a debate-able subject of it relevance in life as living or non-living. A virus cannot produce on its own, does not have a metabolism, and is non-cellular. With all that listed, you would assume it would be a non-living particle. However, once a virus is in tacked with a host, stages of replication begin and can occur quite rapidly.
Most viruses have a nucleocapsid, which includes a protein capsid and the nucleic acid. The protein capsid is a protective shell that surrounds the nucleic acid. Every virus’s genome is either DNA or RNA, never both. The DNA and RNA can be single stranded or double stranded depending on type of genome. Some viruses contain an envelope outside of the capsid, which is a mock version of the host’s cell membrane. Viruses with only with only a nucleocapsid are referred to as naked viruses. Viruses that contain an enveloped are referred to as enveloped viruses.
Enveloped viruses are protected from acid and digestive enzymes that allow the virus to survive in the digestive tract of it host. They have proteins attached to carbohydrates that lie on the outside of the envelop. These are called spikes, which are important in the attachment phase of reproduction.
Viruses have three common shapes. Polyhedral is many sided. Helical, such as influenza virus, is shaped like a rod. Complex is shaped like a spider.
The first step in the stages of replication is called the attachment stage, sometimes referred to as the adsorption phase. The virus receptors, or spikes, attach to the receptor sites of the host cell. If a host cell doesn’t contain receptors for that virus, the host cell is resistant to the virus and can’t be infected.
The second step is the penetration stage. In this stage, the virus or the genome of the virus enters the host’s cell cytoplasm. Then the uncoating process begins. Followed by the uncoating process, the viral synthesis stage occurs. This process of this depends on the genome of the virus. In DNA viruses, the DNA is transcribed into mRNA that goes into the cytoplasm and is translated into early viral proteins. The virus then makes multiple copies of the virus’s DNA. The copies are then transcribed into mRNAs. They get transported into the cytoplasm for translation into late viral proteins. They are then sent to the nucleus for the following stage. In RNA viruses, the RNA stays in the cytoplasm. It creates its own replication and translation of viral proteins. In some viruses, the RNA does go into the nucleus to replicate viral proteins, and then sent back to the cytoplasm for the translation.
The next stage is the assembly stage. Proteins surround the nucleic acid to form the virus’s nucleocapsid. If the virus has an envelop, it will create envelopes in the next stage.
The release stage is the last stage of replication. Some viruses will leave without cell death. Some viruses will leave and the cell dies. When a virus contains an envelop, it will exit the cell with a budding off process. In both naked viruses and enveloped viruses, the release stage results with new viral particles that are released.
Monkeypox virus was first identified in 1958 in monkeys. Monkeypox got its name because it was thought to only be found in monkeys. Then the monkeypox virus was found in an African squirrel, which is now thought to be the natural host. The virus can also infect rats, mice, rabbits, and on rare occasions- humans.
Monkeypox virus is from the genus Orthopoxvirus. It is a zoonotic viral disease and is found in humans mostly in small villages in Western and Central Africa in the tropical rainforest. Most cases were found in Zaire. The first human illness was in Zaire in 1971. A second outbreak occurred in Zaire once again in 1996-1997. In February through August of 1996, 71 clinical cases of monkeypox occurred in 13 villages in Africa. Mostly in the Katako-Kombe area. Six people died during this outbreak. By 1997, 92 people were diagnosed with monkeypox.
In June 2003, an outbreak occurred in the United States. Several residents who have had close contact with prairie dogs became infected with monkeypox. On June 7, 18 residents of Wisconsin, 10 in Illinois, and 1 in Indiana had been infected with monkeypox. By June 9, the Center of Disease Control and Prevention released they had 22 cases of suspected or confirmed cases of monkeypox. By June 11, that number grew to 54 people; 20 in Wisconsin, 10 in Illinois, 23 in Indiana, and 1 in New Jersey. No deaths have occurred from this outbreak in the United States.
In May of 2003, another outbreak occurred in the United States. Every person that was suspected of monkeypox reported being around prairie dogs, which were investigated and found most of the prairie dogs were sick. In late November, 2006, monkeypox virus was found in Gambian rats in Florida, which now considered the cause of the spreading of monkeypox to prairie dogs in 2003.
The cause of monkeypox is transmitted through direct contact with animals that are used for food, through small lesions on the skin, or oral mucous membranes, or through respiratory tract. Humans can also get it though direct contact with the infected animal’s blood, or body fluids. The spread of monkeypox between human to human is thought to be rare, but is possible by respiratory droplets during face-to-face contact, or with direct contact with human body fluids, bedding, or clothing.
The symptoms of monkeypox are very similar to smallpox, but usually much milder. One difference though is monkeypox causes swollen lymph nodes. The incubation period can range from 10-14 days, usually 12 days. An infected person will begin with a fever, headache, muscle aches, backache, swollen lymph nodes, a general feeling of discomfort, and exhaustion. Sometime between 1-3 days after the fever, the infected person with develop a rash, usually on the face but it is not uncommon to see a rash on other parts of the body.
In the outbreak in 2003 in the United States, patients usually experienced a fever, headache, chills, and sweats. About 33% experienced a nonproductive cough. Patients also experience a rash on the head, arms and legs, on bottom of hands and feet.
Monkeypox virus replicates in the lymphoid tissue, much similar to smallpox. The monkeypox virus localizes in the mononuclear phagocytic cells. It is then released into the bloodstream of its host, and then localizes in the skin cells of the virus’s host.
As of right now, there is no safe and proven treatment for monkeypox virus. The smallpox vaccine has been believed to help reduce the risk of the monkeypox virus. The United States Center of Disease Control and Prevention recommends people that are in close contact with animals carrying the virus or infected individuals receive the smallpox vaccination to help protect against the monkeypox virus. People who have been in contact with the virus from an animal or person can receive the vaccine up to 14 days after exposure. People in Africa have been advised to lower their food intake of squirrels and monkeys. Other than that, the only other method of prevention is to be careful of infected animals, wash your hands after contact with infected animals, and avoid intimate contact with infected humans.
Monkeypox is a good example of a changing virus. It was first only infecting animals, but had learned to infect humans. The outbreaks in humans are considered mild, and the death of humans caused by monkeypox is very rare. I believe the virus will become more susceptible in humans as the virus mutates and becomes smarter, because we all know viruses can change. The United States Center of Disease Control and Prevention website has continuous updates of this virus and its outbreaks. So monkeypox is still a concern, but is not yet very common in the United States as it is in Western and Central Africa.

I found this site to be a very creditable source. It did just give a brief description of the virus about the causes, signs and symptoms, the spread in humans, and the treatment and prevention, but I found it help me link my other information together because it filled in the missing information. Many sources I looked at recommended going to this website for more information of the virus.
